I ARTICLE CARRIER Y Filed Feb. 10, 19 67 INVEMTOE HOMER V\/ FORE ER ATTORNEY United States Patent 3,424,368 ARTICLE CARRIER Homer W. Forrer, Jonesboro, Ga., assignor to The Mead Corporation, a corporation of Ohio Filed Feb. 10, 1967, Ser. No. 615,233 US. Cl. 22940 Int. Cl. B65d 71/00, 85/54 9 Claims ABSTRACT OF THE DISCLOSURE Primary packages such as bottles, for example, are made in molds which ordinarily are of a metallic construction. Such molds are substantially permanent in nature although continued use over a long period of time results in tendency toward enlargement of the mold cavities in which the primary packages are formed. This tendency toward enlargement of course is due to many factors but may simply be considered as normal wear. If the mold cavities become larger with extended use, it follows that the bottles formed therein tend to become larger and larger as use of the molds continues.

Article carriers of the wrap-around type such for example as that disclosed in US. Patent 3,128,010 are provided with apertures at the corners thereof for receiving portions of the packaged articles. If bottles tend to increase in diameter and in circumference over a period of time for reasons set forth above, a wrapper of the wrap-around type whose dimensions remain fixed naturally becomes excessively tight as the bottle size gradually becomes greater and greater. Of course one solution to such a situation would be simply to change the die from which the wrapper is cut by enlarging the dimensions thereof in an appropriate fashion. Changing the dimensions of a die is a time consuming operation in itself and furthermore it is necessary to maintain adequate surveillance over the size of the primary packages in such manner that the die dimensions are changed before difficulties arise. Such surveillance, of course, requires an elaborate control sys tem and generally is undesirable.

A principal object of this invention is to provide an improved article carrier of the wrap-around type wherein article receiving apertures at the corners of the wrapper are rendered automatically adjustable so as to accommodate changes in the diameter and circumference of the primary packages.

Still another object of the invention is the provision of an improved article carrier of the type wherein tightening apertures are formed in the overlapping end panels thereof and wherein enlargement of article receiving apertures is effected automatically in coordination with tightening operations of the wrapper.

The invention in one form as applied to a Wrapper type carrier having corner openings comprises means for rendering the wrapper yield'able adjacent the corner openings to accommodate articles of varying sizes. If desired the yielding of the area adjacent the openings may be 3,424,368 Patented Jan. 28, 1969 facilitated by the tightening of the wrapper as the package is formed.

For a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawings in which FIG. 1 is a perspective view of a set-up carrier which is constructed according to the invention; FIG. 2 is a plan view of a blank from which the carrier of FIG. 1 is formed; FIGS. 2A, 2B, 2C, and 2D represent detailed modifications of the blank depicted in FIG. 2; FIG. 3 is a fragmentary perspective view of one corner of the carrier depicted in FIG. 1 and which represents the manner in which a large article is accommodated by the carrier; FIGS. 4A and 4B are fragmentary sectional views taken along the line 44 in FIG. 1; and which shows the carrier as used in conjunction with a small bottle as in FIG. 4A and with a large bottle as in FIG. 4B; FIGS. 5A and 5B are fragmentary cross sectional views taken along the line designated 5-5 in FIG. 1 and represent a carrier as applied to both small and large bottles respectively; FIGS. 6 and 6A are plan views of a carrier blank such as is depicted in FIG. 2 and which represent a modification of FIG. 2.

With reference to the drawings the numeral 1 designates a top panel of the carrier while the numerals 2 and 3 represent sloping shoulder portions which are foldably joined to the top panel 1 along fold lines 4 and 5 respec tively. Formed in top panel 1 are a pair of finger gripping tabs 6 and 7 which are struck out of top panel 1 and are foldably joined thereto along fold lines 8 and 9 respectively. Slits 10, 11 and 12 are struck out of sloping panel 2 while similar slits 13, 14 and 15 are struck out of sloping panel 3. These slits 10-15 receive the caps of the packaged bottles B in a manner well known in the art and serve to enhance package stability. End panel 16 is foldably joined to top panel 1 along a fold line 17 while end panel 18 is foldably joined to top panel 1 along fold line 19. Score lines 20, 21, 22 and 23 .are formed in the blank as shown in FIG. 2 and serve to define a pair of end panel supporting webs 24 and 25 in a manner well known in the art. Similar structure is shown in conjunction with end panel 18 but a detailed description thereof is not deemed necessary.

Carton side walls 26 and 27 are foldably joined to sloping panels 2 and 3 respectively along fold lines 28 and 29. Sloping panel 30 is foldably joined to the bottom edge of side wall 26 along fold line 31 while bottom lap panel 32 is foldably joined to sloping panel 30 along fold line 33. Bottle receiving apertures 34, 35 and 36 are formed in sloping panel 30 and extend somewhat into lap panel 32.

On the other side of the wrapper a sloping panel 37 is foldably joined to side wall 27 along fold line 38 and lap panel 39 is foldably joined to sloping panel 37 along fold line 40. A plurality of bottle receiving apertures 41, 42 and 43 are formed in sloping panel 37 and extend somewhat into lap panel 42.

In order to tighten the wrapper about a group of articles during a packaging operation, a plurality of tightening openings 44, 45 and 46 are formed in lap panel 32 and similar tightening openings 47, 48 and 49 are formed within lap panel 39. As is well known, suitable machine elements enter the tightening apertures and draw the lap panels 32 and 39 toward each other in parallel relationship underneath the bottles B.

In order to form a medial separator for the bottles B in one row from the bottles in the other row a medial panel 50 is foldably joined to lap panel 39 along fold line 51.

For the purpose of securing the wrapper about a group of articles B, a plurality of locking tabs 52-55 formed in lap panel 32 are driven through the openings defined by retaining tabs 56-59 respectively.

The articles B as depicted in FIG. 1 are of normal or initial size and represent bottles made when the metal molds in which the bottles are formed are relatively new. As the molds wear and become larger, the bottles formed therein become larger and larger in diameter and in circumference.

In accordance with this invention, the bottle receiving apertures such as 34, 35, 36 and 41, 42 and 43 are constructed so that they may enlarge somewhat to accommodate larger bottles without weakening the wrapper and without changing the dimensional relationships of the various components of the Wrapper. Thus in accordance with the invention, a plurality of slits 60 and 61 are formed in lap panel 32 and similar slits 62 and 63 are formed in lap panel 39. In addition and in accordance with a feature of the invention, a pair of score lines 64 and 65 are formed on opposite sides of side wall 26 while similar score lines 66 and 67 are formed on opposite sides of side wall 27.

Thus as is best shown in FIGS. 2 and 3 an oversized bottle as depicted in FIG. 3 tends to stretch the end portions of lap panel 32 due to the spreading of slits 60 and 61 and due to the buckling of the small triangle defined by the intersecting score lines 64 and 65. This action in accordance with a main feature of the invention in effect enlarges the bottle receiving aperture 36 and accommodates a larger bottle such as is depicted in FIG. 3 without changing any dimensional relationship in the blank as shown in FIG. 2.

In accordance with another feature of the invention, the openings such as 34 and 36 may be enlarged by the tightening elements which enter the tightening openings 44 and 46. To this end the center line spacing between tightening apertures 44 and 46 as represented by X in FIG. 2 is arranged in the blank so that it is somewhat shorter than the actual spacing between the machine elements which enter these openings so that as the elements enter and move in a parallel direction, the tendency is to stretch the lap panel 32 and to expand the slits 60 and 61. Of course, this action automatically enlarges the apertures 34 and 36. Stretching action of lap panel 32 also tends to enlarge the center aperture 35 but to a lesser degree, the orientation of the slits which define aperture 35 being initially configured and arranged so as to be slightly larger than would be required of the smallest bottle size. Of course the slightly larger configuration of the aperture 35 is feasible because the center bottle associated therewith is in effect captured within the Wrapper and need not be as snugly engaged as do the end bottles.

In accordance with the modification depicted in FIG. 2A the tightening opening such as 46 is provided with a generally triangular shaped entry area 46A and an elongated tightening area 46B. Thus the entry area 46A is sufficiently large to receive a machine tightening element even though the blank might be improperly positioned and upon tightening, the tightening element of the machine slides into the tightening portion 46B of the opening 46 and thus imparts a predetermined degree of tension and stretching action to the lap panel 32.

In accordance with the modification of the invention as depicted in FIG. 2B, straight line slits such as are depicted at 60A and 61A may be substituted for the U-shaped slits 60 and 61 as shown in FIG. 2. A similar slit arrangement is more fully shown in relaxed form in FIG. 6 and in ex panded form in FIG. 6A. Generally speaking the slits are normal to the direction of expansion.

In accordance with the modification of the invention as depicted in FIGS. 2C and 2D, slits such as 60 and 61 are interrelated by a series of weakened lines 70 which facilitate effective stretching of the adjacent material.
